The task of assigning processes to the processor or processors over time, in a way that meets system objectives is called

The task you are referring to is called Scheduling. In computing, scheduling is the method by which processes are assigned to resources, particularly CPU time. It plays a crucial role in operating system design and is essential for achieving various objectives, such as maximizing CPU utilization, ensuring fairness among processes, minimizing response time, and optimizing throughput.

Different scheduling algorithms exist, including First-Come, First-Served (FCFS), Shortest Job Next (SJN), Round Robin, and more advanced techniques like multilevel queue scheduling. Each algorithm has its own advantages and disadvantages depending on the specific objectives it aims to fulfill. Effective scheduling is vital for achieving high performance and reliability in operating systems.
